    Hi,

    I am wondering which box would be a better enclosure for a HT / DVD-A application. I haven't heard either, so I'm basing my opinions on the PDF available at Adire's web site.

    Supposedly, the SBB4 enclosure gives you higher SPLs, while the Adire Alignment goes down deeper. The question is, how much efficient is the SBB4 enclosure? I'll be using the ubiquitous 250W plate amp on a 20x14x12 room, and, as I said, it'll be used for DVD movies and a bit of DVD-A. I want (obviously) the sub to sound very, very powerful, but not at the expense of musicality.

    If someone out there has listened to both enclosures and has an opinon about them, I'd be very glad to listen to it... thanks a lot!

    Javier.

    IMO, Musicality = smooth frequency response and accurate bass.

    If that's the case the AA is more musical at the expense of only maybe a couple decibels in mid bass.

    The SBB4 has some more mid bass punch in the 40-50hz range. The drawback is it can't extend as deep as the AA design and won't be as accurate. The benefits are a small enclosure and a loud sub for rock music bass and home theater punch bass.

    If you like to listen to Jazz with string bass instruments and perhaps pipe organs then the AA design might prove slightly better in music. The AA design has a gradual response capable of deeper bass in the 20hz region.

    I just built the Adire Alignment and it sounds very good with movies and music. Bass is tight and hits pretty good. I have no complaints here!

    I love my AA Tempest!

    It is the most musical sounding sub for the $$$. I am constantly impressed with each viewing of my movies and music.

    The only bad part is that the cabinet will be much bigger than the SBB4.

    Javier,

    When you hear this sub, you will never want to listen to another consumer product sub ever again.

    I guarantee it!

    Scott, Wendell, Chris, Jack----I am building the Tempest 214L AA right now and need help with the 64oz. of polyfill....

    This may sound dumb, but do I just fill it to the top loosely or do I glue and compress it to the sides??

    Am I right to avoid getting it to close to the port tubes and the back of the driver cone??

    Please walk a newbie through this seemingly obvious step.

    I appreciate all input here and do not want to overlook some obvious detail.

    Thanks, Brett

    SBB4 has a "Q" of 0.707. The Adire Alignment has a "Q" of 0.577. So the AA will have 'tighter' better defined, but slightly dryer sounding bass

    About the plate amp, does anyone know if I installing it on the back of an Adire Alignment box would weaken it too much? I worry that it would make the box too flimsy and change the internal volume figures...

    If you are going with the same design of the cabinet from Adire then I will assure you that the integrity of the box will be the same.

    When I first made mine I was always hugging it because it was so big and heavy and just plain scary as a sub.

    Scott, "hugging" it?? Like wrap your arms around it? Or is there another definition I don't know about yet?
